Compiling a kernel under NetBSD is very easy, actually. It is much
more difficult to do under Linux.

First off, remember that the kernel doesn't do any floating point in
the first place, so there is no reason to add any of the FP options
you have there to your mk.conf when building a kernel. Second, the
effect of things like -Os and -fomit-frame-pointer might have odd and
even bad effects. I'd start out by building by moving your mk.conf to
the side. (You might, in general, want to avoid fiddling with
optimization until you know what you're doing...)

You don't need to rebuild the tools if you are running the kernel
build on NetBSD 4 and are building a NetBSD 4 kernel for the same
architecture.

Just go into /usr/src/sys/arch/i386, type "config GENERIC", then
"cd ../compile/GENERIC", then type "make depend && make"
